In 1997, when the U.S. president crashes into Manhattan, now a giant maximum security prison, a convicted bank robber is sent in to rescue him.

I found this on the net. It's the 1981 trailer for the sci-fi actioner EFNY. Great preview that doesn't reveal much except the concept, the character of Snake and the grim, violent, future that awaits us.
This is what made going to the movies so much fun.

Synopsis:

In the future, crime is out of control and New York City's Manhattan is a maximum security prison. Grabbing a bargaining chip right out of the air, convicts bring down the President's plane in bad old Gotham. Gruff Snake Plissken, a one-eyed lone warrior new to prison life, is coerced into bringing the President, and his cargo, out of this land of undesirables.
